Linear diffuser MTL

Description

MTL is a rectangular linear diffuser in aluminium. MTL is

suitable for both supply and exhaust air. MTL is equipped

with air guide baffles, making it possible to use MTL for hor-

izontal supply air. The horizontal dispersal pattern can be

easily changed without the use of tools by turning the air

guide baffle. The air guide baffle must be removed for verti-

cal supply air.

MTL can be supplied in two versions, 15 mm or 19 mm,

depending on capacity requirements or aesthetic considera-

tions. MTL can be installed with plenum box STB/STU inorder to achieve an even flow and individual adjustment.

MTL is normally supplied in lengths up to max. 2 m, but can

be supplied on request up to 5 m. MTZ-1 is a 90o joint,

when an aesthetically pleasing corner is required.

Discrete appearance

Used for both supply air and exhaust

Horizontal and vertical supply air.

MaintenanceMTL can be removed to enable cleaning of internal parts or

to gain access to the duct or box.

The visible parts of the diffuser can be wiped with a dampcloth.

Both ends are equipped with flanges.

Accessories

MTZ-1

MTZ is supplied as two mitred ends (not one piece).

Installation in plenum box STB/STU A self-tapping screw is fitted through the slot up into the

perforated surface of the plenum box.

Installation of slots in continuous strips

The slots are often installed in continuous strips, where

there is a need to join the slots, so that it resembles a single

piece. In these cases, the full length must be specified when

ordering, and the slots will be supplied adjusted to the total

length. The outermost pieces will be equipped with endpieces, and the middle pieces will be supplied without end

pieces. The slots are joined using the accompanying pins.

Technical data

CapacityVolume flow q[l/s] and [m3/h], total pressure p t[Pa], throw l0.2[m] and sound level LWA [dB(A)] can be seen in the dia-

grams.

Throw l0.2Throw l0.2 [m] at a speed of 0.2 m/s and 1 m slot length can

be seen in the diagrams. Correction of throw at other slot

lengths: see table 1.

Frequency-related sound effect levelThe sound effect level in the frequency band is defined as

LWA+KokKok values for MTL without box - see table below.

MTZ is supplied as two mitred ends (not one piece).

BalancingBalancing data for control of air volume is available in a sep-

arate brochure.

Sample calculation:Required data: Volume of air 200 m3/h

2-slot version is selected:

Throw according to diagram: 5.8 m

Throw correction according to table 1:

1.1 x 5.8 = 6.4 m

Pressure loss and sound level accordingto diagram:

Open damper: 13 Pa, 15 dB(A)

Closed damper: 38 Pa, 22 dB(A)

Correction according to table 2:

Open damper: 15 + 2 = 17 dB(A)

Closed damper: 22 + 2 = 24 dB(A)
